-IMPROVEMENT IN Specification forming part of Letters Patent No. 38,792,1lated June 2, 1863.

To aZZ whom it may concerni Beit known that l, CHARLES D. TIsDALE,

0f East Boston, in the county of Sui'olk and State of Massachusetts, have invented an-Improved Railway-Carriage Coupling; and I do hereby declare the same to be fully described l in the following specification and represented in the accompanying drawings, of which- Figure 1 isa side elevation, Figp2va longi tudinal andv vertical section, and Fig. v3f a longitudinal and horizontal section, of it.'A

The nature of my invention consists in the combination of an intermediate elastic link pad]v withthe connection link and the bu'rtenthe i The coupling inquestio'n isa# summing? #gionethat is, one which will connect ltwo car'- riages by and duringtheprocess of bringing them togethergjso-that the couplinglinkotone; may enter abunterof the other ofthem.,l i

In the drawings, .5A A 'exhibit thetwo bunters of the twolcarsV or carriages,"fwhile B isi their link, which, when. the carriages arefinconnection, is coupled to the bunters by. twofpins, O C, which go vertically through..ysuclif` bnnters, and also through the linkyth'ere bef ing one of suchy pins to eacflrfgbunter.l4 A

slider or auxiliary bunter, D, is'arrang'e'd with? in the socket aofeach -bunteran'd in front of a spring, b, which is also ,place lw ithin such socket. Each bunter-socket isjpro'vided with a conical mouth, e, the'front end' of each'bunter-socket being madewith a coiicayity. A pin-passage,v d, is 'made down through the hunter A for reception of a pin, C. f The link has the form shown inFig. 3, or, in lother words, is open, except in having'a bearing, e, extended across its middle part. This plate serves as a rest or abutment tov give support to an elastic cushion, E, through which the link passes, and which is interposed between the two -bunters A A when their carriages are in connection. The link-cushion, being aiiixed to link, serves, by bearing against the bunter head or end, to maintain the'link in or about in ahori'zontal position preparatory to erally-.incre or less on its pins, and subserquen'tlyoperates to restore the link to its nor. lna1position. -It also answers-the purpose of a spring "or fender -to 'relieve the shock of contact of the two'bunters.. By raising the pin of either bunterfso as to dsengage it from the other the auxiliary bunter within that bunter containing the raised pin will be shot for-l ward by its spring, and will project by or .across the pinpassage in such manner as to Ahold up the ypin or prevent its descent. By

'bringing the'prinnary hunters together so as Ato force the link into that one from which it*- maylie-disconnected the projecting end of -the'link will be forced against the'free auxil iary bunter, and so as to pressit backward andrelieve the pin, which, by its .'gravitating power, will f-be caused to fall down intozthe link, andtherebyconple the bunt'ers'together.

I am aware that it is not new, and, consequently, do notclaim, to combine witha buntgfl adevicefnot only for;supportin'gthelinkf v pin when ra'liisedjtherein, butt-capable' o fbeing moved from underneath such pin .by the llink in the process o f'vforcing-.the link into the bunter, the same; beingso as '.to set free the pin,

in order thatvitfm y be caused by gravity to fall down through." the link,y and thereby couple the two hunters together. A

What I claim, however, is-

The combination of theintermediate elasticv cushion or link-pad,-E, with` the link B and the bunter A, the said link-pad being affixed to the link, and so as to operate as specified.
